Which One Doesn't Belong? - Acid-Base Properties - Directions
Using the Which One Doesn't Belong? - Acid-Base Properties Concept Builder is quite simple. There are three difficulty levels. Every question in each difficulty level has the same idea. You are presented with three to five statements about the properties of acids and/or bases and you must identify the one property that is not like the others. You can identify the outlier by tapping on it. When you tap on one of the representations, a box appears around it to indicate that it is the currently-selected answer option. If you change your mind, then tap on it a seond time to deselect it or tap on another option answer. A Check Answer button is visible as long as one answer option is selected. Once you are satisfied with your choice(s) of an answer, tap on the Check Answer button. Your answer(s) will be evaluated and your Progress Report will be updated.
Your goal is to earn "Stars" and to complete one or more difficulty levels. Stars are earned when you show success on a particular question. If you miss a question then you will have to answer two similar questions correctly before earning a star. Once you show success on all the questions for a particular difficulty level, you will earn the trophy for that difficulty level.
